INSULATOE.

1,070,151. Specification of Application filed March 14, 1912.

T 0 all whom 'iif-r/tag concern Be it known that I. \Vnmin ll. Morris, residing at Uliltlll. in the county of Mendocino and State of California, have a new and illl proved Insulator, of which the following: is a specification.

This imention is in. the nature of an improved glass insulator for telephone and telegraph service, and. it consists in the peculiar construction and arrangeuwntot parts hereinafter fully explained. specifically pointed out in the ap 'ieuded claims and illusl l l invented trated in the accompanying drawing, lll:

which:

Figure l, is a perspective view of a portion of a pole, and a cross arm with my improved construction of insulator applied to the said cross arm. Fig. '2. is a longitmiinal section of the insulator taken substantially on the line 2 on Fig. '1. Fig. 3. is a transverse section thereof on the line 3-3 on Fig. *2. l? 4, is a perspective View of the several parts that constitute my im proved insulator separated from each other. in its practical arrangement my improved insulator comprises two wire clamping membors having; opposing corrugated surfaces, the upper one having convexed portions 10 for seating in the concaved depressions 20 in the lower member The clamping menn bers .1 and 2 a re ot' glass or other analogous material. and the lower member has pendent flanges 21 that lap over the. opposite edge of the ross arm 3 for assisting in keeping the members 1 and 2 in place and for preventing water from getting under the glass member 2. By corrugating the opposing faces of the, members l and 2 they mesh with each other and serve to positively crimp the wire between them. and thereby lirmly clamp the said wire.

t designates a sheet metal cover or housing" that fits over the top insulating member l... the latter having a rounded upper taco, as shown. The ends ot the housing are bent at right angles to form toot hinges 40 through which pass clamp bolts 5 that extend through the cross bar and are made fast by the thumb nuts 50.

7 designates a packing of fibrous material Gopies or" this patent may be obtained for the top of the between the housing and member 1 and which consists in holding down the member 1 under ordinary expansion of the housing 4'.

From the "foregoing taken in connection with the drawing. the complete construction, and advantages of my invention will he readil understood.

What I claim is:

l. in combination with a supprni'. an insulalor comprising a vitreous body formed at an upper and a lower section. the opposing' 'laces ol which have intermeshing portions \\hereb to grip and crimp a wire tlierehetween. the lower section having pendout flanges tor lapping the opposite edges of the support. a sheet metal covering on the vitreous body having end flanges for engaging the support. and means for securing the flanges on the support.

9. in combination with a support, an insulator comprising a vitreous body formed of an upper and a lower section, the. opposing faces of which have internieshing' portions whereby to grip and crimp a wire therebetween. the lower section having pendent. flanges for lapping the opposite edges of the support. a sheet metal covering on the. vitreous body having end flanges for engaging the support. means for securing the flanges on the support. and alibrous lining between the covering and the. vitreous body.

In combination with a supporting" arm; an insulator comprising an upper and a lower section of vitreous n'iaterial. the opposing faces of the said section having inter-meshing corrugations whereby to crimp the wire that is held between said faces. the lower section having pendent flanges tor lapping over the opposite edges of the sup-- porting arm. a sheet metal cover. for the insulator sections. said cover having apertured flanges for seating on the support. bolt. and nut devices for securing the said llange on the supporting arm, and a fibrous lining between the vitreous body and the cover.
